Coordinating evidence across jurisdictions in a complex investigation
We created a single evidence and response protocol for an investigation involving companies, accounts and professional advisers in several jurisdictions.
Requests from the Spanish authorities covered transactions documented under different legal systems and in several languages.
A fragmented response risked inconsistency, duplication and disclosure of material without the necessary context.
The challenge
- Large volumes of records held in different countries.
- Local legal concepts with no exact Spanish equivalent.
- Confidentiality and privilege considerations.
- Overlapping deadlines and information requests.
Our approach
Technical precision, focused on the client.
Central evidence room
Documents were collected once, indexed by issue and linked to the transaction chronology.
Local-law explanations
Overseas counsel supplied focused notes explaining the legal effect of key documents and arrangements.
Response governance
A review protocol ensured that every submission was factually consistent, proportionate and aligned with the defence strategy.
The outcome
The client gained control of a dispersed record and could respond efficiently without losing the wider narrative.
The indexed evidence base supported technical submissions and remained ready for later appeal or court proceedings.
International evidence becomes persuasive only when it is organised around the legal questions the authority must decide.
